Earth Day is about living more sustainablyâmaking choices that are, in a sense, more âgreen.â That idea can apply to your finances, too, particularly when it comes to choosing investments that reflect your values.
Thatâs the idea behind ESG investing, along with related strategies such as faith-based funds and impact investing, which let you support or avoid certain industries. Whether you care most about climate, corporate behavior, or simply bringing your investment choices more in line with your principles, there are ways to invest with both purpose and discipline.
ESG stands for âenvironmental, social, and governance.â Investors whoâve heard the term ESG investing often think of it as a single strategy. But itâs really just another way to evaluate a company: It means looking at how the company handles environmental issues, treats workers and customers, and runs its business. In practice, that might mean choosing ESG-focused mutual funds or exchange-traded funds (ETFs), or picking individual stocks that reflect your priorities.
If you want something more hands-on, some funds take a simpler approach by avoiding certain industries altogether. That might mean steering clear of tobacco, weapons, or fossil fuels. Many faith-based funds follow this model, using specific ethical guidelines to decide what goes into (or comes out of) a portfolio.
Other investors go a step further and aim for a specific outcome by buying into impact funds. These vehicles focus on companies or projects tied to things like clean energy, community development, or expanding access to financial services.
Whether you want to steer clear of particular sectors, support specific causes, or focus on companies with stronger practices, you have options. The challenge isnât finding a single ârightâ approach. Itâs deciding what matters most to you.

As ESG investing has grown, so has the debate about its effectiveness. Thereâs no single standard for what qualifies as ESG, and different funds can take very different approaches.
That ambiguity has fueled criticism. Some see ESG as a way to push social or political agendas through investing, while others view it as a practical way to evaluate risks tied to issues such as climate change, labor practices, or corporate governance.
It also leaves room for greenwashingâwhen companies or funds overstate their environmental or social credentials. For investors, that means looking beyond the label to see how a fund selects its investments and what it actually owns.
Performance is another point of debate. Some investors worry that focusing on ESG means giving up returns, while others see it as a way to identify risks and opportunities that donât always show up in traditional financial analysis. In practice, results can vary depending on how a fund is constructed and what sectors it emphasizes.
ESG funds can take very different approaches. Before you invest, take a closer look at how a fund defines sustainability and how that shows up in its holdings.
If youâre interested in ESG investing, the next step is figuring out how to apply it. That starts with defining your priorities and understanding the options available to you.
You donât need a perfect solution to get started. Even small adjustments, such as switching funds or shifting allocations, can help bring your portfolio more in line with your priorities.
